"This was a terrible buy.
The trigger broke, the trigger post broke, a gear stripped, the motor connectors broke, and it messes up constantly. DONT BUY!!

"I bought 3 of these gearboxes 3 weeks ago. They were used for approx 10 games. 2 of the 3 gearboxes broke. Both of them broke in the same spot. The trigger trolley stop peg broke. Thus making catastrophic failure. The metal used in these gearbox' sis cheap pot metal. I am waiting for the 3rd gearbox to break now. These are in g&g combat machine bodies.

"Gearbox internal review:

Gearbox shell - 3.5/5
The gearbox shell itself honestly doesn't seem that strong; I also own the Matrix QD gearbox, and it is a LOT stronger. Also, in order to fit my SHS 13:1 gear set, I had to shave off some parts with a Dremel, so if you plan on replacing the gears, I hope you have a Dremel. Definitely not the shell for a DMR set up, but I think it'll stand up to anything lower than an M120 or lower perfectly fine.

Air seal nozzle - 5/5
The stock air seal nozzle is FANTASTIC!!! It's made of CNC aluminum, it's strong, it's lightweight, and provides a VERY nice air seal. Definitely the most impressive stock air nozzle I've ever seen. I would like to note, however, that it absolutely refused to fit onto my SHS cylinder head.

Cylinder head - 4/5
Very good stock cylinder head. It's made out of polycarbonate, but the stem is made out of a nice aluminum. It provides a nice air seal with the stock cylinder; add some Teflon tape and you won't even need to buy another cylinder head. It comes with a nice, thick SorboPad pre-installed; nice touch, though it doesn't completely correct the AoE.

Cylinder - 4.5/5
Good cylinder. It's metal, some kind of shiny-ish silver. It's nice and smooth on the inside, so less friction between it and the piston head. It has a port meant for a standard M4 inner barrel (363mm), which doesn't really suit my 509mm inner barrel, so I switched it out. However, if it fits your inner barrel length, there is absolutely no reason to replace it.

Piston head - 4/5
It's a really nice polycarbonate piston with eight ports, but the o-ring SUCKS BUTT FLUPS. GET ANOTHER PISTON O-RING FROM HOME DEPOT FOR THE LOVE OF GLOB. Once you do, it provides a very, very good seal, no need to replace this piston head either.

Piston - 3.5/5
Standard stock piston. One steel tooth, rest of out made of polycarbonate, last tooth removed to help with AoE. It should serve you just fine, though replacing it to better suit your set up is a good idea.

Spring - works as a spring
It's a spring. It provides springy powers. I didn't chrono with it as I immediately changed the spring, sorry to disappoint. If I had to guess, it's either an M110 or M120.

Spring guide - 3.5/5
It has a metal base with smooth, metal ball bearings, which is nice, but the shaft is made of polymer. This is the same for the Matrix QD gearbox. I just don't see why they can't just make a metal one.....

Gears - 3.5/5
I'm not using these gears; as mentioned, I'm using SHS 13:1 gears. These gears seem to be an 18:1 ratio, but honestly, they don't seem too robust. But like I said, I'm won't be using them, so I can't test them. They come pre-installed with a sector chip.

Wiring - 5/5
It comes with low-res wiring, and the trigger contact is awesome! Definitely don't need to replace the wiring.

Other stuff:
Mine came with a broken trigger. Don't know if that's APS's or UPS's fault, but it's worth mentioning.
As stated above, I had to do some Dremeling to fit my SHS 13:1 gears.
The blowback doesn't fit with my G&P upper receiver, though I wasn't expecting it to, so it's fine.

"So far this gearbox is fantastic. Very solid. Being able to remove the spring before taking the box apart helps tremendously. But the best part is not having to put the spring back in until after you put the box back together. I dont know if i got lucky or what but mine is shimmed perfectly. I thought something was wrong when i first shot with it because it was so quiet. Decent grease job. Air nozzle has o-ring. Steel bushings. Much improved blow back system. Now if APS would just make that spring guide metal instead of plastic... but at least it has bearings. I had no compression at all when i checked. Replaced the o-ring on the piston head and that fixed the problem. don't know what the deal was there.

Things to note: Spring guide is plastic but has bearings. AOE needs to be improved. Compression should be checked out of the box. Cylinder head only has 1 o-ring. Fits great in APS bodies (duh). I believe Javelin as well. Not so sure about others.

Over all this thing is a great buy at this price.

"quality gear box

workmanship is up there with the best ive seen.

shimmed really smooth.

installed into matrix m4 with 363mm 6.04 brass barrel

blowback plate not used, removed blowback spring from top of gear box

very nice fit.

swapped out oem spring for matrix m130

running 11.1v 1300MHA 15C BATTERY with matrix high torque motor.

puts .23gr bb through one side of 5 gallon bucket at 50ft, sometimes both side.

VERY SATISFIED

its such a quality gear box that i purchased the APS ASR 110 m4 today as it also has a hybrid gear box only difference is 7mm bearings instead of 8mm.

"This gearbox by far worth the money i put it on my Javelin M4 CQB and it has well over the power to punch through two soda cans! 5/5
